数学と言うよりも英語の問題のような気がするんだけれど…

>1. five more that the absolute value of a number
この英文、たぶん間違っているよね。正しくは
five (is) more than the absolute value of a number
じゃないかな。だとすれば、
ある数をAとすると、
|A| < 5

>2. the additive inverse of a number increased by its absolute value.
-|A|

>3. the additive inverse of the absolute value of twice some number.
-2|A|

>4. the absolute value of the sum of two numbers.
二つの数をA、Bとすると
|A+B|

>5. the sum of the absolute value of two numbers..
|A|+|B|

>6. The absolute value of the difference of x and y is greater than 5.
|x-y| > 5

>7. Three times the absolute value of a number is 8.
3|A| = 8

>8.The absolute value of the sum of two numbers is less than the square of their sum
|A+B| < √|A+B|

ちょっと私から質問なのですけれども、英文の意味は分かるんですよね？
